Award Biodegradation & Composting Marine Degradable

Kaneka Wins Japan Bioindustry Award 2019 for Seawater Biodegradable Bioplastics

The poly-hexanoate-butyrate (PHBH) copolymer is produced by Kaneka from plant oil using a recombinant strain of Cupriavidus necator at a capacity of currently 1,000 tons, with plans to increase production to 5,000 and later to 100,000 tons a year.

PHBH materials decompose not only on soil, but also in seawater (90% within 6 months at 30°C) and have obtained the “OK Biodegradable Marine” certificate from TÜV AUSTRIA Belgium NV.

The biopolymer-producing strain is based on joint research by Yoshiharu Doi, former Professor of the Tokyo Institute of Technology and Director at RIKEN, and five Kaneka researchers who will share the award of 3 million ¥ (~25,000 €).

About JBA

Japan Bioindustry Association (JBA) is a non-profit organization established in 1987.

The organization is planning for sound development in bioscience-related industries and is dedicated to solving problems on a global scale through advances in bioscience.

JBA is contributing to society in various areas from the development of advanced technology to the development of industry.

Japanese bioindustries have developed with a base in the traditional fermentation industry.

However in recent years advances in biotechnology have been made in various fields and this in turn has had an impact on numerous corporations.

JBA’s membership base spans a wide array of corporations that use applications of biotechnology in areas ranging from pharmaceutical and medical supplies, food and cosmetics, as well as chemicals, information, machinery, construction and energy and natural resources.

In addition, JBA counts public organizations, universities, public research institutes and a variety of individuals as members.

Hence JBA is a unique organization able to comprehensively promote the advancement of bioindustries through the cooperation of industry, academia and government.
